Triple H spray foam crew went out to this home in Dix Hills, NY where the homeowner just did some renovations on his home and wanted to insulate the new extension. Closed cell spray foam is very different. Because it adheres to all surfaces, expands in place, and air cannot pass through it, it not only stops air flow through all the holes and cracks in the building assembly and materials, but it is superior insulation. In the end this new space that is now properly insulated will be a much more comfortable interior space with less drafts.
